If your system is unresponsive or your energy bills are spiking, schedule service with our certified technicians to restore your comfort.
Is a Thermostat Replacement in Your Future?
Thermostats are an important part of your home’s infrastructure that you may not think much of until they experience an issue. Often, older thermostats are working past their estimated lifespan, and that is when they begin to show signs they may warrant a replacement.
No matter the age of your thermostat, look out for:
- Inaccurate Readings: The device displays a temperature that doesn’t match the actual air in the room.
- Unresponsive Interface: The screen stays blank or buttons fail to trigger the air conditioner.
- Short Cycling: Your HVAC system turns on and off too frequently due to faulty sensor data.
- High Energy Bills: An outdated controller causes your unit to run longer than necessary.
- Obsolete Technology: Older manual sliders lack the precision of modern digital controls.

We diagnose communication issues between the thermostat and the HVAC control board. Our technicians identify loose wiring and replace faulty internal components to get your system back online. If a repair is not cost-effective, we provide clear options for a modern upgrade.

I had RS Andrews come out to address several electrical items that were identified during the inspection when selling my home, and I couldn't be happier with the service I received.
My technician, Zac, was outstanding. He took the time to explain everything he was doing and, more importantly, why it needed to be done.
Zac not only completed all of the required inspection repairs, including installing GFCI protection where required by code both inside and outside the house, but he also identified and corrected a few additional electrical issues that were related to the inspection items.
He was professional, knowledgeable, courteous, and took pride in his work from start to finish. It's not often you find a technician who combines technical expertise with excellent customer service, but Zac certainly does.
I highly recommend RS Andrews, and if you have the opportunity to request Zac, I would do so without hesitation. He made what could have been a stressful part of selling a home a very positive experience.

My wife and I are elderly, and summer nights without air conditioning is almost unbearable. Our air went out at night, on July 1, and we called RS Andrews. They sent a very pleasant, knowledgeable young man out, and he repaired our system in short order. We were very pleased with both the repair service and the price. If you have work to be done, you can call Andrews 24/7, and expect quality service at a reasonable price.

I had another leak in my basement bathroom and RSAndrews came out the same day to repair and replace some pipes. Their professionalism from the time I called “How can I brighten your smile “ was so impressive and amazing. The plumber was so informative. I was so happy I used RS Andrews instead of my home warranty Choice Homes

The install was a complete furnace and AC unit. From the estimate to the install everything was done as promised and timely. There was initially some confusion regarding my thermostat but that was resolved and taken care of. Update 11/18/22 Chris is great! He's been here before and is very professional and knowledgeable. He took the time to diagnose an issue we've had and is working to resolve it 11/28 Chris is still great they are still finding issues and resolving them as quickly as possible. 5/9/23 Bill and his son came to move a gas line for a new stove. This was done quickly, properly and they were both professional. Nice job 9/28 Chris is still awesome. He is thorough and identifies and resolves any issues that arise.
3/15 Tim was the service tech. Thorough polite and professional. Great job

Kalvin was great! He was very professional while explaining future tune ups and code requirements. I believe my present unit is approximately 16 years old and perhaps sometime in the near future best think about replacing the unit altogether. Good information to have, I'll keep Kalvin's recommendation under consideration.

RS Andrews did an excellent job and helped improve my air quality with an ultraviolet light in the downstairs furnace. I had previously had one installed upstairs and after 8 years, no mold. but after seeing the mold that accumulated downstairs RS Andrews Installed an ultraviolet light in that furnace system. Well worth the investment!
